Niels Bohr (1885-1962)
Danish physicist, Bohr was born in Copenhagen, in 1885, and died also in this city in 1962. Bohr graduated in his birth city, in 1911, and worked with J. J. Thomsom and E. Rutherford in England. In 1913, by applying the atomic model of Rutherford, was able to understand some of the spectral series of hydrogen and the structure of the periodic system of elements. He announced the correspondence principle and, in 1928, the complementary principle. Bohr studied the liquid drop nuclear model, and before the discovery of plutonium, foresighted its fission property, similar to that of U-235.
Bohr received the Nobel Prize of Physics in 1922.
